But the morning of the adventure found the boy in me climbing the first ascent-rather steep and hard, to the applause of all Adams and Eves in the troop.

Half way through we started finding snow all around us but, the boy in me by then was once again lost into oblivion. I found myself lagging behind and often falling down on the soft snow due to soft foam rubber soles of my shoes.
A laughing stock I was. But, soon I found strong healthy arms supporting me. I pleaded, “Let me go, I’ll not be able to make it”, but they would not let me. They were the arms of two hill folks who as people, had been described as withdrawn, selfish and aloof my friends from the plains.
